From this moment the block 2-is caused'to participate in the rotation of the small block 44 until the hill 4. of the hook 4 brings allvthe mov-- ing devicesto rest by entering the recess 5 inthe body of the fuse. 1 1 I When, for anyreason the hook 4 has become fast in the recess 5 before the tooth l6 encounters the projection 25 the 1 parts are brought to rest bythis lattercontact.

If for any reason, such. as incomplete insertion, of theqprojectile, defective friction of .the movable. ring and so forth, one of the two driving members should not act, the parts in question will be brought to rest and the gunner, after at most a second revolution, of the handle, (which takes place idly) is notified ofthe factthat the fusehas not been set. i i

The apparatus described can be fixed to guns with vertical axis, forwhich apparatusit is only necessary to, modify the form ofthe fitting for thecarrier of. the setting device and-thearrangement of the adjusts. ing scales in order to facilitate their reading.

Figs. 16, 17 and .18 illustrate an embodiment of the invention meeting these requirements. i i

By meansof. a member 33, thesetting centering socket 45 is fixed on the carrier andlserves as a bolt for the small block 44 :1 of the setting device is rotatable in the block 2 andis mounted with a special gripping device 52 for fixing the projectile durmg setting.
